SpaceX launches two NASA astronauts to spacefor the first time in historic US mission
SpaceX has begun new chapter in the history of United States space flight.
Elon Musk's private space company on Saturday launched NASA (astronaut) Bob Behnken and Doug Hurley into orbit, successfully (begin) SpaceX's first crewed mission.The company's Falcon 9 rocket and Crew Dragon spacecraft took off from NASA's Kennedy Space Center in Florida 3∶22 p. m.ET.The capsule is the first (private) designed and built spacecraft (carry) astronauts to space and is bound for the International Space Station.
Beyond the achievement for SpaceX, the launch represents the first time NASA(launch) its own astronauts since the end of the space shuttle program nearly a decade ago.
"It was (incredibly), " NASA astronaut Bob Behnken said of the launch moments after the spacecraft reached orbit."Appreciate all the hard work and thanks for the great ride to space."
Known as Demo2, the launch represents the culmination of SpaceX's work thus far. Musk (found) the company in 2002 and has since declared its informal credo to be "making humanity a multiplanetary species." To date, SpaceX has launched dozens of satellites and spacecraft, before Saturday, it had never put a human in space.
Katherine Johnson whose life was described in the movie Hidden Figures died on February 24, 2020, aged 101. The 2016 movie describes a real story of a female African-American mathematician who joined the National Aeronautics and Space Administration(NASA) and led a mission to put the first man on the moon in the 1950s when racial discrimination was widespread.
"NASA is deeply saddened by the loss of a leader from our pioneering days," said NASA administrator Jim Bridenstine on the webpage of NASA. "Ms. Johnson helped our nation enlarge the frontiers (边界) of space and she also played an important role in opening doors for women and people of color to explore space. At NASA we will never forget her courage, leadership and the achievements we could not have reached without her. "
Johnson was born in West Virginia in 1918. She graduated from West Virginia State University as a mathematics major and became a teacher at a public school. She was also the first African-American woman to attend graduate school in mathematics at West Virginia University. But less than one year later, she left school to focus on raising children.
Her life changed in 1952 after a long career break. A relative told her about open positions at the all-black West Area Computing section at the National Advisory Committee for Aeronautics's Langley laboratory, and she began to work at Langley the next year. NASA depended on humans for complicated aerospace(航空航天) calculation as there was no high-functioning electronic computer. Female mathematicians usually took the job as their salary was lower. Johnson was one of those African-American human computers.
Johnson was initially in charge of aerospace analysis and assigned to a space development mission launched in 1958. Then she worked for the 1961 suborbital (亚轨道的) flight of astronaut Alan Shepard and the 1962 orbital flight of John Glenn. Johnson continued to participate in missions after she retired in 1986. Her hidden achievements were finally publicized when former U.S. President Barack Obama granted her the Presidential Medal of Freedom in 2015 and her dramatic life was made into a movie.
Many Tuesday mornings I have coffee with my father. Although my father is a man of few words, I really1the time along with him.
One recent Tuesday, I found it a bit2when I rang the doorbell, no one seemed to be home. After climbing in through the window, I3through his home, checking every room. I tried not to4. Yet, upstairs, downstairs, no Dad anywhere.
I was worried.5, my father was seventy-one years old. Anything could have happened to him. Then, I got in my car and drove to my mother's aerobics (有氧运动) class.
On the drive, I thought a lot about our history together. Suddenly, I was three years old and he was6me up to the living room window to see the Christmas lights. In his7, I was safe and secure. Then I was twelve and my dad was8all the kids at my birthday party with his magic tricks. I was so9of my father for being so talented. He'd made my party a10.
As I entered my mother's class, I was nervous. My mom looked at me in11. "Mom, where's Dad?" I asked, "He's working in the12on the side of the house!" she answered.
And I hurried to my car and13back to the yard. "Hey, Dad!" I yelled out and told him about my fears of the last half hour. And so, as I14the door to my father's house, we went inside for our usual cup of coffee.
Thanks, Daddy, for all the15and more importantly, for all your love.
China Shows First High-definition Pictures of Mars Taken by Tianwen-1
The China National Space Administration made public on March 4, 2021 the first high-definition pictures of Mars taken by the nation's spacecraft.
The pictures — two black-and-white and one colored — were shot (recent) by China's Tianwen-1 robotic probe when spacecraft was travelling in Mars' orbit, according to the administration.
The two black-and-white (image) were taken by the high-definition camera on Tianwen-1's orbiter when the probe was about 330 to 350 kilometers above the Martian surface. The colored picture was generated by another camera on the orbiter, (show) Mars' north pole.
As the first (independence) Mars mission of the country, Tianwen-1 (launch) by a Long March 5 heavy-lift carrier rocket on July 23, 2020 from the Wenchang Space Launch Center in Hainan province, starting the nation's planetary exploration program.
The probe, consists of two major parts — the orbiter and the landing capsule — has successfully landed on Mars.
It entered (it) preset parking orbit above Mars and flew in this orbit for about three months releasing its landing capsule, said the administration.
All of the seven mission payloads (有效载荷) on the orbiter were activated during the probe's stay in the parking orbit (carry) out scientific tasks and also to observe and analyze the landforms(地貌) and weather of the best landing site.
Pumpkin (南瓜) carving at Halloween is a family tradition. We visit a local farm every October. In the pumpkin field, I compete with my three brothers and sister to seek out the biggest pumpkin. My dad has a rule that we have to carry our pumpkins back home, and as the eldest child I have an advantage — I carried an 85-pounder back last year.
This year, it was hard to tell whether my prize or the one chosen by my 14-year-old brother, Jason, was the winner. Unfortunately we forgot to weigh them before taking out their insides, but I was determined to prove my point. All of us were hard at work at the kitchen table, with my mom filming the annual event. I'm unsure now why I thought forcing my head inside the pumpkin would settle the matter, but it seemed to make perfect sense at the time.
With the pumpkin resting on the table, hole uppermost, I bent over and pressed my head against the opening. At first I got jammed just above my eyes and then, as I went on with my task, unwilling to quit, my nose briefly prevented entry. Finally I managed to put my whole head into it, like a cork(软木塞) forced into a bottle. I was able to straighten up with the huge pumpkin resting on my shoulders.
My excitement was short-lived. The pumpkin was heavy. "I'm going to set it down, now," I said, and with Jason helping to support its weight, I bent back over the table to give it somewhere to rest. It was only when I tried to remove my head that I realized getting out was going to be less straightforward than getting in. When I pulled hard, my nose got in the way. I got into a panic as I pressed firmly against the table and moved my head around trying to find the right angle, but it was no use. "I can't get it out!" I shouted, my voice sounding unnaturally loud in the enclosed space.

I was stuck for five or six minutes though it felt much longer.
That video was posted the day before Halloween.
